From drone, aeroplane or helicopter, photographs are taken. Multiple overlapping photographs of the ground are taken. Precise measurements from the photographs can be taken to create topography maps.</SPAN></SPAN></P><P STYLE="margin:0 0 14 0;"><SPAN><SPAN>This data was collected using a drone carrying a digital camera in 2020.</SPAN></SPAN></P><P STYLE="margin:0 0 14 0;"><SPAN><SPAN>A software package was used extract points (X,Y,Z (x & y coordinates) and z (height)) from the photographs.
